If -no-hs-main is specified in --make mode, attempt linking even when
there's no Main module.

Fixes bug #686620

MERGE TO STABLE

Support strictness annotations on data declarations and support the record
and infix constructors. Also tweaked the pretty printer a bit.

Remove un-necessary case

-------------------------------------
	 	Two minor wibbles
	-------------------------------------

[These two unrelated fixes just got tangled together in my tree.]

1.  Fix a crash when a class op is used as a record selector

2.  Fix a wibble related to the new DataCon naming story.
    In tcId, treat the DataCon case entirely separately, because
    its "stupid context" doesn't show up in its type.

    On the way, remove the DataCon cases in tcLookupId and tcLookupGlobalId
    The should not be necessary.  He says hopefully.

Cosmetic wibble

Comments only

Fix build on GHC < 5.00

make use of MBLOCK_ROUND_DOWN()

arenaAlloc(): tidy up alignment calc

More notes about building on Win32

Use hasktags by default

Restore interrupt/quit signal handlers after every evaluation in GHCi,
just in case the program set its own.

Comment change only

GHC is pre-supposed in order to build GHC.  We weren't making this
nearly as explicit as it should have been.

Emit an error if we're trying to build GHC from source without GHC installed.

Not sure if this fix is correct, but at least this module compiles
again...

-------------------------------------
   Do the top-level tcSimpifyTop (to resolve monomorphic constraints)
   once for the whole program, rather than once per splice group
	-------------------------------------

This change makes the trivial program

	main = return ()

work again.  It had stopped working (emitting an error about Monad m
being unconstrained) because the 'checkMain' stuff (which knows special
things about 'main' was happening only *after* all the groups of
decls in the module had been dealt with and zonked (incl tcSimplifyTop).

Better to postpone.  A little more plumbing, but one fewer unexpected
happenings.

Comments

A bit more debug info + comments

A bit more about scoped type variables

wibble

Fix for deriving of records with leading underscore, and corresponding lex

support many more MachOps in the PowerPC NCG

upd wrt spacy filenames

Commit a couple of hi-boot files I forgot

Be sensitive to filenames containing spaces when processing
:load & :add commands. Ditto when interpreting filenames given
on GHCi's cmd-line.

Merge to STABLE.

Threaded RTS: improve ccall performance by allocation parameters as a
variable length array instead of using malloc

Enable building the native code generator for PowerPC/Mac OS X by default.
It's still not used by default, so you have to specify -fasm when you want
it.

Finally enable GHCi by default on Mac OS X, this should have been done a
long time ago...

MERGE TO STABLE

A wibble to the constructor-naming story

Another typo.

Typo.

-------------------------------------
  Big upheaval to the way that constructors are named
	-------------------------------------

This commit enshrines the new story for constructor names.  We could never
really get External Core to work nicely before, but now it does.

The story is laid out in detail in the Commentary
	ghc/docs/comm/the-beast/data-types.html
so I will not repeat it here.

	[Manuel: the commentary isn't being updated, apparently.]

However, the net effect is that in Core and in External Core, contructors look
like constructors, and the way things are printed is all consistent.

It is a fairly pervasive change (which is why it has been so long postponed),
but I hope the question is now finally closed.

All the libraries compile etc, and I've run many tests, but doubtless there will
be some dark corners.

Fix two bugs/omissions in the new THUNK_SELECTOR code which cause
biographical profiling to fall over.

(aka rev. 1.135.4.10)

Fix bug caused by non-use of function prototypes (grrr!).

Adapt the dist target a little to work with the nightly build's new
way of building source dists.

It now works by building a link tree to the build tree, and doing
'make dist' on the link tree, to avoid destroying the real build tree.
This just needed a couple of tweaks to the dist target to work.

Lots of new stuff about data types

More Win32 notes

Mac OS X:
Add support for dynamic linker "symbol stubs". For every function that might
be imported from a dynamic library, we have to generate a short piece of
assembly code.
Extend the NatM monad to keep track of the list of imports (for which stubs
will be generated later).
Fix a bug concerning 64 bit ints (hi and low words were swapped in one place).

Tighten up prev commit:
- win32: only add default --template=... option if the template file
  exists.
- if user has supplied --cc=.., use it as a default for 'ld'.
